Here is the call graph for this function:

int UnixDevIOCTL	(	NUTDEVICE *	dev,
		int	req,
		void *	conf
	)

Perform USART control functions.

This function is called by the ioctl() function of the C runtime library.

Parameters:

dev	Identifies the device that receives the device-control function.
req	Requested control function. May be set to one of the following constants: UART_SETSPEED UART_GETSPEED UART_SETDATABITS UART_GETDATABITS UART_SETSTOPBITS UART_GETSTOPBITS UART_SETPARITY UART_GETPARITY UART_SETFLOWCONTROL UART_GETFLOWCONTROL UART_SETBLOCKREAD UART_GETBLOCKREAD UART_SETSTATUS UART_GETSTATUS
conf	Points to a buffer that contains any data required for the given control function or receives data from that function.

Returns:

0 on success, -1 otherwise.

Warning:

Timeout values are given in milliseconds and are limited to the granularity of the system timer. To disable timeout, set the parameter to NUT_WAIT_INFINITE.
